England Building Death Traps: Overheating Crisis Warnings 2026

England risks constructing a new generation of death trap buildings that can fatally overheat unless the government tightens standards and prioritises climate safeguards, planning experts have said. Fears are growing about the plight of vulnerable people in heatwaves, with research this week suggesting that 2,700 people had died in the May and June heatwaves in England and Wales.

Why Overheating Buildings Are a Deadly Threat

Only about half of local plans being drawn up by councils and local authorities require new buildings to have a cooling or ventilation strategy to prevent overheating, according to findings from the Royal Town Planning Institute (RTPI) and the Town and Country Planning Association (TCPA). While nearly all English councils say they intend to include green infrastructure in new housing developments – such as trees that can cool streets or provision of access to waterways – only about a quarter of them use a recognised tool that would ensure this.

“This is a matter of life and death,” said Celia Davis, interim director of operations at the TCPA. “We need to avoid building death traps.” She warned that although many local authorities had high aims for dealing with heat, this was not always borne out in practice. “There is a gap between what they say they want and what they achieve,” she said.

Key Findings from the RTPI Report

The RTPI report, entitled Local Plans and the Climate Crisis, used AI to assess local plans from English councils, including those already adopted and those still under consideration. While the authors acknowledged that the use of AI was “experimental” in such a report and had the potential to result in some inaccuracies, the RTPI said it was confident that the method gave a broadly reliable picture.

Government Response and Future Standards

Earlier this year, ministers unveiled the “future homes standard”, a new set of regulations that will govern how houses are built from 2028, and which includes provisions for keeping homes warmer in winter and cooler in summer. But the standard will not apply to buildings such as schools, hospitals, and care homes, leaving vulnerable populations at risk during extreme heat events.

What Can Be Done to Prevent Overheating?

• Implement mandatory cooling strategies in all new buildings
• Expand green infrastructure like trees and water features
• Apply heat safety standards to schools, hospitals, and care homes
• Use AI tools to monitor and enforce local climate plans
